ElectroFlex : Concept design of a tool lanyard with integrated power cable.Mastroianni, Benjamin, Babic, Oliver January 2019 (has links)
For a company that focuses on the use of battery power, the integration into fossil fuel dominated markets can be challenging. In order to help with integration into new markets, Globe Group AB are developing job-essential accessories that are compatible with their tools and batteries. The purpose of the work done in this thesis was to develop a concept for a tool lanyard with an integrated electrical cable that is compatible with Globe Group AB’s current line of power tools. During this project it was decided that the research and testing would be conducted and analyzed based off high altitude tree work done by arborists. This thesis focuses on the evaluation of research and testing to aid in concept design. A large focus was laid on the implementation of physical testing into early research and development stages, in an attempt to increase the validity of design decisions. The project was carried out by doing preliminary research and testing in order to gain information and metrics that could be used in the concept and prototype design stages. The prototypes were tested and compared to data collected prior in the project, to make statements about the feasibility of the concept and it’s included features. The result of this project was a final concept that includes all features that were deemed necessary through research and testing, a physical prototype, and test data to offer proof of concept.

User-centered design of an attachable battery pack for arboristsPersson, Kasper January 2019 (has links)
Globe Group, a company under the brand Greenworks Tools, is one of the industry leaders in battery-powered outdoor equipment, developing tools that deliver the performance of a gasoline-powered tool without the hassle and emissions associated with it. Gasoline-powered tools are still prevalent in the field of arboriculture where arborists work daily with chainsaws while performing tree felling and pruning. Now a new type of chainsaw is in development by Globe Group which is characterized by its lightweight and large battery capacity, which brings extraordinary battery life. This feature is possible by redesigning the chainsaw to support an external battery, which is housed in a separate battery pack instead of placing the battery directly inside the tool. The aim of the project is to adapt and design the battery pack for arborists by using a user-centered design approach with focus on ergonomics. This is done by having a close cooperation with the arborists during the whole project, from pre-study to final concept evaluation, to explore and fulfill the needs of the user. By using a wide range of research and design methods, a final concept is developed to reach the needs of the user and company. / Globe Group, som står bakom varumärket Greenworks Tools, är branschledande inom batteridriven utomhusutrustning och levererar verktyg med samma prestandanivå som hos ett bensindrivet verktyg, fast utan utsläpp och krångel som det typiskt är förknippat med. Bensindrivna verktyg är fortfarande mycket vanliga inom trädvårdssektorn där arborister arbetar med motorsågar dagligen vid trädfällning och grenbeskärning. Nu är en ny typ av motorsåg under utveckling av Globe Group som kännetecknas av sin lätta vikt och stora batterikapacitet, vilket ger extra lång batterilivslängd. Denna kombination är möjligt genom att ha ett externt batteri vilket är huserat i ett separat batteripaket istället för att placera batteriet direkt in i verktyget. Projektets mål är att anpassa och konstruera batterifickan specifikt för målgruppen arborister genom att använda en användarcentrerad designapproach med fokus på ergonomi. Detta görs genom ett nära samarbete med arboristerna under hela projektets gång, från förstudie till utvärdering av resultat, för att utforska och uppfylla användarens behov. Ett slutligt koncept är utvecklat för att tillgodose både användarens och företagets behov/krav.
